Regarding the Mario missing stars hack, you have to apply the patch to your rom.
Full details can be seen over at romhacking.net, heres a quick rundown of what to do...
Applying the patch
------------------
You'll need a Mario 64 US (NTSC) ROM, usually called "Super Mario 64 (U)!.z64"
in order to play this hack. Here's how you should proceed:
1) Extend your ROM with VL-Tone's Mario 64 ROM Extender:

If you are on Linux, you can try also Cellar Dweller's "alternate" extender:

http://www.romhacking.net/utils/356/ (there's also a Mac version hosted at the
same site)
The ROM should be loaded on the "ISO file" field (PPF is a format designed for
the Playstation, but works very well for N64 ROMS too) and the .ppf file on
the Patch field.
Note: If you are a Mac user, you'll have to use the ROM Extender v1.3b, which has
been released a few days ago (at the moment of this writing).
I can't even get SM64 - Missing Stars to show up in the launcher. Is there anything special i have to add to Surreal.ini? Or do you have to rename the rom? Would be great if someone could give me hint on this one...
